语言和视觉空间任务上的性别差异引起了人们极大的兴趣，假设男性和女性之间存在半球偏侧性差异。一些检查性别差异的功能成像研究表明，男性在语言任务上更偏左，而女性在视觉空间任务上更偏右；然而，研究结果并不一致。在这里，我们使用功能磁共振成像来研究三十名参与者，在语音和视觉空间任务中匹配任务表现。对于每项任务，都使用感兴趣区域分析来测试大脑偏侧性的差异。结果表明，存在侧化差异，男性在语音任务中更多地向左偏侧，在视觉空间任务中表现出更大的双侧活动，而女性在语音任务中表现出更大的双侧活动，并且在视觉空间任务中更多地右侧化。我们的数据提供了明确的证据，证明男性和女性在处理语言与视觉空间信息时存在偏侧性差异。 (c) 2006 Elsevier Inc. 保留所有权利。
Sex differences on language and visuospatial tasks are of great interest, with differences in hemispheric laterality hypothesized to exist between males and females. Some functional imaging studies examining sex differences have shown that males are more left lateralized on language tasks and females are more right lateralized on visuospatial tasks; however, findings are inconsistent. Here we used functional magnetic resonance imaging to study thirty participants, matched on task performance, during phonological and visuospatial tasks. For each task, region-of-interest analyses were used to test differences in cerebral laterality. Results indicate that lateralization differences exist, with males more left lateralized during the phonological task and showing greater bilateral activity during the visuospatial task, whereas females showed greater bilateral activity during the phonological task and were more right lateralized during the visuospatial task. Our data provide clear evidence for differences in laterality between males and females when processing language versus visuospatial information. (c) 2006 Elsevier Inc. All rights reserved.
